 note = {Determination of platinum (Pt) derived from cisplatin in tissues was performed by electrospray ionization mass spectrometry (ESI-MS) using silver (Ag) as the internal standard. Pt and Ag reacted with diethyldithiocarbamate (DDC), and were extracted using isoamylalcohol and acidified with oxalic acid. The compounds were termed Pt(DDC)3 + and Ag(DDC)2 +, based on their m/z values exhibiting the highest peaks at m/z 639 and m/z 405, respectively. The limit of detection was 30 pg and the quantitation range was from 100 to 10000 pg using 5 mg tissue. The present method allowed the determination of Pt in wet-ashed tissue in 10 minutes.},
